wow nice game. good balance, manie enemies, manie buildings with different health. bosses, good game play, nice usefull powerups, nice upgrade's .. has it all!
I had to figure out the final boss though I was a bit oblivious to its rear end, I though I had to get him through the center. when I figured it out it was doable.
I dont understand the haters. so what that its based on an existing game, really there are hunders of flash games based on another game who cares about that seriously.
very nice game, maybe a tad to easy, but that is actually also nice, so next time you could implement level modes.. easy normal hard
